Note: This counter is based on chip 74xx93 (counter) used as a frequency divider by 8 the maximum bandwidth for arduino to count is 8 Mhz and we can multiply this number using 74xx93 or any other ...

Hitachi’s HD44780 based 16×2 character LCD are very cheap and widely available, and is an essential part for any project that displays information. Using the LCD backpack, desired data can be ...

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...

To connect an LCD to an Arduino without using an I2C module, you'll need to connect the LCD directly to the Arduino using its parallel interface. Below is a guide to help you achieve this: ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

This Project describes the implementation of a digital frequency meter using Arduino to determine sinusoidal frequency signal in the range of 20Hz to 5kHz.

Hi, I had the problem of making a ferquency counter but the component does not work. Why not use a microcontroller (PIC) with I2C port to achieve this frequency counter ? The choice of the input ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...
